Analysis of Defects on Railway Constructions and Sections by Help of Higher Order Spectra

The paper submitted deals with the investigation of failures of railway structures by means of the Method of higher orders spectra. The reason why Method of higher orders spectra is prospective in future is that unlike other non-destructive methods this one offers a high-quality information on the existence of non-linear processes in material and geometrically complex investigated samples (structures) and thus also the information on the existence and degree of development of particular faults. A timely detection of the level or location of a failure of a structural member or of the entire structure is gaining its importance at present due to the increasing maintenance costing. The application of this method will also offer the source materials about real material and geometrical characteristics of engineering structures in existing numerical models.
